Leading Yukawa terms in the three-loop anomalous dimension and four-loop $β$ -function of $N = 1$ supersymmetric theories for various renormalization prescriptions

Ratmir Jumanov, Konstantin Stepanyantz

For an arbitrary renormalizable $N = 1$ supersymmetric theory with a single gauge coupling regularized by higher covariant derivatives we calculate the three-loop contribution…

A condition for the reduction of couplings in the $P = \frac{1}{3} Q$ supersymmetric theories

Mikhail Kuzmichev, Konstantin Stepanyantz

We demonstrate that in the $P = \frac{1}{3} Q$ supersymmetric theories the renormalization group invariance of the ratio $λ^{ij k} / e$ (of the Yukawa couplings to the gauge coupling) is…

Exact $β$ -functions for $N = 1$ supersymmetric theories finite in the lowest loops

Konstantin Stepanyantz

We consider a one-loop finite $N = 1$ supersymmetric theory in such a renormalization scheme that the first $L$ contributions to the gauge $β$ -function and the first $(L - 1)$ c…
